  • Thanks Perry,Going to try two formulations with XG at 1% and 2%.Does it usually hold up well up to 50c?And yes, ditto on the packaging... However the client already has them so trying to figure out a way for it to work before telling them to get new…

Hey Perry, It's a moisturizing cream with: 65-70% Waters 5% Cetearyl Alcohol / Polysorbate 60 3% Cetyl Alcohol 6-7% Butters (Shea, Cocoa, etc.) 12-13% oils including Menthol 0.5% Xanthan Gum Hope this helps, thanks in advance! Th…
  • We have a simple freezer and an incubator ($300 or so, small) that we use for freeze/thaw and heat stability (40c, 50c, etc.) I'd also love to get into in-house challenge testing. Anyone with ideas on how we can begin would be great. Thanks!
  • Hi all, A quick update. I did about 6 samples so far. The best so far has been Xanthan Gum at 0.5%, with PEG-40 at 3% to assist with emulsion. Still doing some heat studies... there are some very specific heat requirements due to the geographic ar…
  • @EVchem, that sounds like a good idea. Would you recommend keeping my existing waxes at their current levels, but replace some water phase with the polymeric emulsifiers? Would adding much more Polysorbate 60, for example, help with this? I am goin…
  • Thanks @letsalcido, Extra info: Because of the smaller volume in R&D, these samples are being agitated by a stick blender. Do you think the extra 15% added post-formulation could result in the entire water/oil phase separation? I am trying to…
  • Hi all, A quick update. It seems as though the product is completely separating at 40~c. (Not just the 15%).
  • @Abbot, thanks for the recommendation. Any ultrasonic blender recommendations? Also, I can lower the oil content if that will work better. I only need about 2%-3% oil... I was following a study that was done, that's why my oil was higher. But it ca…
  • Thank you gentlemen. I will look for pure lecithin.Matt: Apologies, we do use two pots and heat them both, and we are currently adding the oil to the water while being blended.So Pot 1: Water, Lecithin, Xanthan GumPot 2: OilsPot 2 into Pot 1. (Oil i…

 @Pharma, thanks for your input. I'll try some different versions of Lecithin and see if there's one with a lot more information. And yes this emulsion is a sprayable edible product, which is why I had the question about Citric Acid…

 Thanks for the input. I will start experimenting with this. Is there another substance I can use to lower the PH that won't affect taste?
  • Hey all, Thanks for your input. Details: I am using this liquid lecithin in the tests. Process: 1. Add Lecithin and Xanthan Gum to water.2. Heat3. Blend together.4. Add oil while blending.5. Add preservative when cooled. Initially the emulsion seem…
  • Hi All, Thanks for all the suggestions, ideas, and dialogue.  Recent Update: 36 hours later, the latest change (original formula with different agitation) seems to have solved the issue. (Image) @tanelise I generally seal the jars when the c…
  • Hello all, Okay last night did an additional test. Using the original formula posted here, I hand-mixed until 85 degrees Fahrenheit and then poured one sample, then poured an additional sample and hand-mixed that individual sample in its individual…
  • Hi all, 28 hours later update: Both samples have the same caking issue. Photos below. 1. Shea Butter 2%, Stearic Aid 1%. Still caking/pasting. I am beginning to wonder if it's the way the formula is being agitated after combining water and oil ph…
  • Hi All, Thanks so much for the assistance. I have done two more test samples. Right now (as with the rest of the creams), the texture is almost as desired and will probably reach it within the day. But we will see how it works in the next 24-48hrs.…
  • @ozgirl Thank you for your response. Yes, each jar is immediately covered/sealed with a lid. Three photos below: (Apologies, the photographs posted out of order) #3 Shows some of the cakey quality. It's not creamy. However, if I mix it up, it r…
  • @ngarayeva001 Thanks for your input! We did formulate without the aloe and extract and the end result was still cakey. I don't know if there is a common culprit when it comes to caking, like not enough emulsifier or a bad balance.
  • @Herbnerd & @Pharma & @Entropic_Cocci Thanks for your input. We haven't started on this yet but I will definitely try what you've suggested. You are right, it would be an oral product that a client is requesting. Thank you!
  • Hello everyone. I've recently been beginning doing some formulations for a few clients on a small basis. I've read some posts here and there are some extremely helpful individuals, and the course on this site looks very good. Thanks!
